Abstract: Three methods for improving catalyst activities in residue hydrogenation were summarized. The modulation acidities are introduced by assistants on support,such as P,B and rare earth. The reaming effect of reaming agent,hydrothermal method and nano-assembly method on supports were presented. Furthermore,the role of surfactant on the dispersion of active metal was reviewed with CA and EDTA as a representative complexing agent. Besides,the application status of modified catalysts in residue hydrogenation process was reviewed,the development direction of new nano catalytic materials was pointed out,and then the development of catalysts was combined with modern analysis methods to do further mechanism research. It is expect to provide theoretical basis for modification research of hydrogenation catalyst,and also improve heavy oil treatment process.
